Should speakers hum when they're connected to a stereo, but the volume of is turned all the way down?

No Stupid Questions@lemmy.worldEnglish · 2 days ago

I have some old speakers in the house that I wanted to test. So instead of messing with the real stereo unit from the 80s, I bought a $30 stereo from Amazon, and new speaker wire.

The speakers sound okay, but there’s a hum coming from them all the time. Even with the stereo volume knob turned all the way down. Is this normal for stereo systems and I just haven’t noticed?

I’ll try the tricks! I’m betting the volume knob / potentiometer is a cause.

Update: twiddling the knob does nothing.
